What is Generative Engine Optimization (GEO)?

The Rise of Answer Engines

Users are migrating from traditional query-and-click search engines toward interactive answer engines such as ChatGPT Search, Perplexity AI, and Google AI Overviews. Instead of scanning a page of ten links, users read an AI-generated paragraph that combines facts from multiple online sources.

How Generative Engines Choose Sources

Research from Princeton University and top information retrieval labs demonstrates that generative engines prioritize sources that provide:

• Authoritative Schema Metadata: JSON-LD markup that defines author entities, corporate organizations, and product specifications.
• Factual Density: High information-to-noise ratio with concrete metrics and clear definitions.
• Clean Machine Readability: Lightweight HTML rendered without blocking scripts or crawler restrictions.
